notes
*1 : The values of n, m are specified to offer 6.144 Mbps after the AAL1 PDU header (1 byte) is added. These values remain for further study in case that AAL type 5 is employed and/or FEC is employed.
*2 : Clock relation is shown in Figure 1.
*3 : The mapping from TS packet to ATM cell in AAL5 is for further study.
*4 : These can be selected for AAL type1.
